Description
The Trane TRR02429 Transformer is an electrical control component used to step down incoming voltage for safe operation of low-voltage circuits. It operates with a 277V primary input and delivers a 24V secondary output at 75VA rating. Within HVAC systems such as air handling units, rooftop equipment, and control panels, it is placed in the electrical compartment to supply regulated power to thermostats, relays, and control boards. It uses electromagnetic induction through primary and secondary windings to maintain stable voltage conversion, supporting consistent control circuit operation and dependable system response during continuous usage.
